Problems - plants shriveling
I recently re-aquascaped my tank and now my crypts (Wendtii green and brown and some other ones I'm not sure of) are starting to shrivel up. The leaves get shiny and see-through and die off. I can't seem to find a solution to this.
The tank is a 20-high with 2 compact fluorescents. I don't know my water parameters off hand but can get them if needed. I do 25% water changes every 2 weeks and use Tetra's Flora Pride about once a month. I'm really not going all out for a true, awesome planted tank, but my plants were doing fine until about a month ago when the crypts started shriveling.
I also have a bunch of wisteria, which is doing great, a vallisneria which seems to be doing fine and 2 other types of plant that are currently unidentified (whoops).
Can someone help me out here?
